To aZZ/womitmdy/ concern'.

Be it known that I, PEARL E. SnLnr, a citizen of the United States, and a' resident of Portsmouth, county of Sciotgstate of Ohio, have invented certain new and use ful Improvements in -Shoe Shanks, of which the following is a full, clear, and exactdej l scription.

sole 'tread portion and shank portion of the sole. l

Figure 1 is a top plan view of a shank ,constructed and arranged. in accordance with the present invention; A

Figure 2 is a. side edge view thereof;

Figure 3 is a bottom plan view of a shoe, a portion of the sole and heel being removed to show my improved shank in service relation;

Fi re 4e is a cross section taken as on the line 1r-f1 in Figure 3.

As seen in the drawings,r the relatively wide metal shank 9 has aila'ttened heel portion 10, and a thin broadly convex portion 11 and a relatively fiat portion 12 adjacent thereto. Intermediate the portions and 12 the etal is narrowed or waisted and at this portion is provided with the-outwardly or downwardly projecting full ridge'13 and the heli ridge 14. Between the ridges 13 and 14.` is a relatively flat, though narrow section 15. The surfaceof'the section 15 is substantially level with the section 16, the two sections forming a firm suport lengthwise of the arch'of the shoe or the insole 17 thereof. This construction prevents the insole from falling away from the line at Among the principal objects whchthef present invention has in view are: to pro? vide a rigid support for-the outeredge of a.y shoe coincident with the arch thereof; 5to.' provide a rigid supportfor the insole 'of a' Iterial formed to conform to and support which .thcshoe was lasted, and avoids the filling usually adaptable for a similar purpose.

If desired the valley 18 at the upper'side of the 'shank formed by the depression of' the rid e 13 maybe provided with filling materia of the usual ty e.

.At the outer edge o the shoe thefwelt 19 extends lengthwiseof the arch under that portion of the ootlmowh as the outer edfjre ofthe arch.. `The .inseamed portion' of t e welt" heretofore vhas been unsupported and consequently, to a material extent, the foot has had no solid foundation upon which to rest at this part of the shoe. Y

When using the present invention the ridge 14 extends laterally jas seen best in Figures 3 and 4 of the drawingsover the inner edge of the welt 19, the extent to which the ridge 14 may cover the Welt19 being ontional with the designer, but in all cases it will be found that the welt andthe portion of the shoe adjacent thereto is supported by the rigid shank.

The prforations 2O shown in the drawings are/provided to receive nails or other securing devices. e laimsz.

1. A shoe shank constructed of rigid mathe insole of a shoe, and a plurality of lon, Y git-udinal ribs on said shank, said ribs being variedvin height to imparta pitch to said shank when applied conforming to the line on which the shoeis lasted.

2.1 A shoe shank constructed of rigid material formed to conform to and support the insole of a shoe when appliied, a longitudinal central rib on said s ank, and a relatively shallow rib at one side of said shank,

.parallel to said central rib and adapted to enege under and support the outer welt of a s pe at the insole.
